Abstract
This study presents a detailed evaluation of a dual-band communication system for a Martian rover, designed to operate with 2.4 GHz antennas for control and sensor data, and 5.8 GHz antennas for high-bandwidth video transmission. Extensive simulation-based analysis was conducted in CST Microwave Studio to optimize impedance matching, antenna placement, and inter-system isolation. Several positioning strategies were explored, revealing trade-offs between gain and coverage uniformity, particularly when mounting antennas directly on the chassis versus elevated on masts. Dual-antenna configurations, implemented at both frequencies, proved effective in enhancing signal stability, mitigating nulls caused by structural interference, and preserving link integrity across various rover orientations. System-level evaluations demonstrated that the 2.4 GHz control link offers reliable omnidirectional coverage with low power requirements. In comparison, the 5.8 GHz video link, supported by a high-gain base station antenna, provides robust communication.
